Blocked drain driving you mad? Don’t panic. Here’s what’s likely causing it — and how A1 Plumbing & Gas can fix it fast.
Most Common Causes of Blocked Drains in Goulburn
- Tree Roots in Pipes
Goulburn’s older properties are often surrounded by trees. Roots easily invade cracked pipes and cause major blockages. - Grease Buildup
Pouring cooking fat down the sink? Over time, it solidifies and clogs your kitchen drain. - Foreign Objects
Baby wipes, paper towels, sanitary products — none of these belong in your toilet. They’re common blockage culprits. - Hair and Soap Scum
Over time, hair combines with soap to slow drainage — especially in showers and bathroom sinks. - Poor Pipe Installation or Collapse
Old clay or poorly installed pipes may sag or collapse, especially after heavy rain or shifting ground.
